Taking it, treating it – returning it to nature

We collect around 1,271 million litres of wastewater from three million households and 200,000 businesses, every day in the North West.

When you flush it, pour it, pull the plug and drain it away, your wastewater goes on a journey back to nature – which starts the moment it leaves your property and enters our sewerage system. 

 

Collecting and treating sewage

Wastewater collected from homes and businesses is transported along our 72,000 kilometres of pipes and sewers to one of our 560 wastewater treatment works, all dedicated to cleaning up in-coming wastewater so that the treated water can then return to rivers and to the sea.

 

 

Sewer flooding

Sewer flooding is unpleasant and distressing and we spend money every year to help prevent it from happening.

There are many different reasons why a flood can occur and the impact it has on our customers can vary, with the numbers of flooding incidents that occur each year being heavily influenced by the weather.

For these reasons we have developed a sewer flooding index which assesses the impact of sewer flooding on our customers.  The index looks at both the cause of the flooding and the impact of the flooding, on properties, outside spaces or repeat flooding.

The number of flooding incidents that occurred in our region in 2016/17 was heavily impacted by two very severe storms in June and September, which affected major urban areas and resulted in large numbers of flooding incidents.  This has resulted in a significant increase in the overall number of properties that flooded in the year and has also meant that we have not been able to achieve the target for our flooding index.

Over the next five years we're aiming to reduce levels of flooding, improve our index score and continue to help to reduce the impact of sewer flooding on customers.
